Found some confusing numbers here, but I'm sure everyone else has looked and there isn't much. One source says 165,037 Mustang produced for 1995, another says 190,994. I know there weren't 30g Cobra's produced that year, so that is not the discrepency. Another source says 70,126 GTs produced for that year.
Maybe someone else can help, but since the V6, V8 and Cobras have different engine codes in the VIN, are their unit numbers engine specific? For example, in a V6 VIN, do the last 5 numbers represent only V6 cars, or all Mustangs in the VIN year produced?
If the unit number is engine code specific then the 70,126 GTs number may help you out. Good luck!
